BACKGROUND INFORMATION

1. Field of the Invention

The present invention relates to a series of heteroaryl-substituted pyrrole derivatives which have excellent inhibitory activity against the production of inflammatory cytokines such as interleukin (IL)-1, IL-6 and IL-8 and tumor necrosis factor (TNF), particularly IL-1β and TNFα. As a consequence, the compounds of the present invention have valuable anti-pyretic, analgesic, anti-viral and anti-inflammatory activity and are useful in the prophylaxis and treatment of autoimmune diseases such as chronic rheumatism, bone diseases such as osteoporosis and the many other diseases in which the above-described inflammatory cytokines take part. The invention also provides methods and compositions using these novel compounds as well as processes for their preparation.

2. Background Information

Non-steroidal anti-inflammatory drugs (NSAIDs) have ben widely used for the treatment and prophylaxis of various inflammatory diseases and in pain relief because they have, as their main pharmacological activity, anti-pyretic, analgesic, and anti-inflammatory activity which is based on their ability to inhibit the biosynthesis of prostaglandin (PG) the inhibition of cyclooxygenase activity. Another class of compounds commonly used for the treatment of rheumatoid arthritis is the disease-modifying anti-rheumatic drugs (DMARDs), sample of which include methotrexate and sulphasalazine. This is a wide class of drugs in which the compounds have no common mechanism of action. For the treatment of chronic rheumatism, NSAIDs are used nosotropically and DMARDs are used etiotropically. There are a number of problems associated with these classes of drugs. Conventional NSAIDs can induce undesirable side effects including gastrointestinal disorders such as gastric ulcers and renal disorders, resulting in difficulties for any patient who has to take such a drug for an extended period of time. DMARDs can also induce undesirable side effects including nausea and diarrhoea and, furthermore, they have not yet been clearly shown to exhibit a stable, long-lasting effect.

A class of active substances generally called cytokines, which are produced in the body by immunocytes, has recently been found. One group of cytokines is known as the inflammatory cytokines and it includes interleukin (IL)-1, IL-6 and IL-8 and tumor necrosis factor (TNF). The inflammatory cytokines have been demonstrated to play a major role in a number of biological processes. These include action as an inflammatory mediator through the stimulation of the arachidonic acid metabolic pathway leading to the production of PG, the migration of leukocytes, the production of acute phase protein, and activation of osteoclasts.

It is believed that the inflammatory cytokines are associated with many diseases including inflammatory diseases and the induction of bone resorption. Due to their mechanism of action, which is different from that of conventional drugs such as those described above, compounds which are able to inhibit the production of inflammatory cytokines are expected to provide an improved new generation of anti-pyretic, analgesic and anti-inflammatory drugs and medicaments for the treatment of autoimmune diseases such as chronic rheumatism, bone diseases such as osteoporosis and the many other diseases in which the above-described inflammatory cytokines are believed to take part.

Compounds which are said to demonstrate inhibitory activity against the production of inflammatory cytokines include various heteroaryl compounds [see, for example, WO 96/21452, WO 97/5877, WO 97/23479 and J. Med. Chem., 39, 3929-3937 (1996)]. Examples of compounds of this type include the following:

There is a need for further compounds having improved activity, pharmacokinetics and safety, and it is this need which is addressed by the present invention. Compounds having the characteristic bicyclic amino group of the compounds of the present invention have been neither disclosed nor suggested in the prior art

SUMMARY OF THE INVENTION

It is therefore an object of the present invention to provide a series of new compounds which inhibit the production of inflammatory cytokines and consequently show anti-pyretic, analgesic, anti-viral and anti-inflammatory activity and have utility in the prophylaxis and treatment of autoimmune diseases such as chronic rheumatism, bone diseases such as osteoporosis and the many other diseases in which the above-described inflammatory cytokines take part.

It is therefore an object of the present invention to provide a series of new pyrrole derivatives having a novel bicyclic amino substituent which inhibit the production of inflammatory cytokines and consequently show anti-pyretic, analgesic, anti-viral and anti-inflammatory activity and have utility in the prophylaxis and treatment of autoimmune diseases such as chronic rheumatism bone diseases such as osteoporosis and the many other diseases in which the above-described inflammatory cytokines take part.

These esters and other derivatives are compounds of formula (I) in which a functional group (for example, a hydroxyl group, an amino group, an imino group or a sulfonamide group) of said compound of formula (I) is modified by the addition of a protecting group using conventional techniques well-known in the art (see, for example, “Protective Groups in Organic Synthesis, Second Edition, Theodora W. Greene and Peter G. M. Wuts, 1991, John Wiley & Sons, Inc.).

There is no particular restriction on the nature of this protecting group, provided that, where the ester or other derivative is intended for therapeutic purposes, it must be pharmacologically acceptable, i.e. the protecting group must be capable of being removed by a metabolic process (e.g. hydrolysis) on administration of said compound to the body of a live mammal to give a compound of formula (I) or a salt thereof. In other words, the pharmacologically acceptable esters or other derivatives are pro-drugs of the compounds of formula (I) of the present invention. Where, however, the ester or other derivative of the compound of formula (I) of the present invention is intended for non-therapeutic purposes (e.g. as an intermediate in the preparation of other compounds), then the requirement that said ester or other derivative is pharmacologically acceptable does not apply.

Whether an ester or other derivative of a compound of formula (I) of the present invention is pharmacologically acceptable can be easily determined. The compound under investigation is intravenously administered to an experimental animal such as a rat or mouse and the body fluids of the animal are thereafter studied. If a compound of formula (I) or a pharmacologically acceptable salt thereof can be detected in the body fluids, the compound under investigation is judged to be a pharmacologically acceptable ester or other derivative.

The compounds of formula (I) of the present invention can be converted to an ester, examples of which include a compound of formula (I) in which a hydroxyl group present therein is esterified. The ester residue may be a general protecting group where the esterified compound is to be used as an intermediate or a protecting group which is capable of being removed by a metabolic process (e.g. hydrolysis) in vivo where the esterified compound is one which is pharmacologically acceptable.

It should be noted that the specific combination of substituents R¹, R² and R³ shown in the above Tables 1 and 2 can also be applied to the substituents R¹, R² and R³ in formulae (I-2), (I-4) and (I-5) above.

The compounds of formula (I) and pharmacologically acceptable salts, esters and other derivatives thereof of the present invention can be prepared according to a variety of processes well known in the art for the preparation of compounds of this type, for example as described in the following Methods A to M below.

Method A

Method A is a method to prepare compounds of formula (I-1) of the present invention.

In the above formulae, R¹, R² and R³ are as defined above.

Step A1

In this Step, a pyrrolidine compound of formula (3a) is prepared by reacting an aminonitrile compound of formula (1a) with an α,β-unsaturated aldehyde compound of formula (2a). This reaction is well known in the field of synthetic organic chemistry and can be carried out using well known techniques, for example according to the method described in EP 0733823, the contents of which are incorporated herein by reference thereto.

In more detail, this Step is carried out in the presence of a base. There is no particular restriction on the nature of the bases used, and any base commonly used in reactions of this type may equally be used here. Examples of such bases include: alkali metal hydroxides, such as lithium hydroxide, sodium hydroxide and potassium hydroxide; alkali metal hydrides, such as lithium hydride, sodium hydride and potassium hydride; alkali metal amides, such as lithium amide, sodium amide, potassium amide and lithium bis(trimethylsilyl)amide; and alkali metal alkoxides, such as lithium ethoxide, sodium methoxide, sodium ethoxide and potassium t-butoxide. Of these, we prefer the lithium amides.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include: aliphatic hydrocarbons, such as hexane and heptane; aromatic hydrocarbons, such as benzene, toluene and xylene; ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane; and alcohols, such as methanol, ethanol, propanol, isopropanol and butanol. Of these, we prefer the ethers.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −78° C. to 100° C., more preferably from −78° C. to room temperature. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 30 hours, more preferably from 1 hour to 20 hours, will usually suffice.

Step A2

In this Step, the desired pyrrole derivative of formula (I-1) of the present invention is prepared by the elimination of hydrogen cyanide and water from the compound of formula (3a) prepared in Step A1 above. These reactions are well known in the field of synthetic organic chemitry and can be carried out using well known techniques, for example according to the methods described in detail in EP 0799823.

In more detail, this may be achieved by heating the residue obtained by distilling off the solvent from the product of Step A1, or by heating the material obtained by extracting that residue, washing it with water and distilling off the solvent, preferably at a temperature not lower than 100° C., in the presence or absence of a solvent after completion of the reaction of Step A1. The reaction proceeds sufficiently in the absence of a solvent, but, when a solvent is used, the solvent is preferably inert and has a higher boiling point. Examples of suitable solvents include: toluene, xylene, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, diglyme and diphenyl ether.

The two steps of Method M can be carried out according to the methods described in detail in O. Pollet et al., Heterocycles, 43, 1391 (1996) and Anet et al., Austral. J. Scient. Res., <A3>, 635-640 (1950), the contents of which are incorporated herein by reference thereto.

After completion of each of the reactions described in the steps of Method A to Method M above, the desired compound may be isolated from the reaction mixture in a conventional manner. For example, it can be obtained by neutralizing the reaction mixture as needed, removing insoluble matters by filtration, if any are present, adding organic solvents which are not miscible with each other, such as water and ethyl acetate, washing with water or the like, separating the organic layer containing the desired compound, drying it over anhydrous magnesium sulfate or the like and then distilling off the solvent.

If necessary, the desired compound thus obtained can be isolated and purified by using a conventional method such as recrystallization or reprecipitation or by a chromatographic method. Examples of chromatography include adsorption column chromatography using a carrier such as silica gel, alumina or magnesium-silica gel type Florisil, chromatography using a synthetic adsorbent, for example, partition column chromatography using a carrier such as Sephadex LH-20 (product of Pharmacia), Amberlite XAD-11 (product of Rohm & Haas) or Diaion HP-20 (product of Mitsubishi Chemical), ion exchange chromatography and normal-phase-reverse-phase column chromatography (high-performance liquid chromatography) using a silica gel or alkylated silica gel. If necessary, two or more of these techniques can be used in combination to isolate and purify the desired compound.

The present invention encompasses esters and other derivatives of the compounds of formula (I)′. These esters and other derivatives are compounds of formula (I)′ in which a functional group (for example, a hydroxyl group, an amino group, an imino group or a sulfonamide group) of said compound of formula (I)′ is modified by the addition of a protecting group using conventional techniques well-known in the art (see, for example, “Protective Groups in Organic Synthesis, Second Edition, Theodora W. Greene and Peter G. M. Wuts, 1991, John Wiley & Sons, Inc.).

There is no particular restriction on the nature of this protecting group, provided that, where the ester or other derivative is intended for therapeutic purposes, it must be pharmacologically acceptable, i.e. the protecting group must be capable of being removed by a metabolic process (e.g. hydrolysis) on administration of said compound to the body of a live mammal to give a compound of formula (I)′ or a salt thereof. In other words, the pharmacologically acceptable esters or other derivatives are prodrugs of the compounds of formula (I)′ of the present invention. Where, however, the ester or other derivative of the compound of formula (I)′ of the present invention is intended for non-therapeutic purposes (e.g. as an intermediate in the preparation of other compounds), then the requirement that said ester or other derivative is pharmacologically acceptable does not apply.

Whether an ester or other derivative of a compound of formula (I)′ of the present invention is pharmacologically acceptable can be easily determined. The compound under investigation is intravenously administered to an experimental animal such as a rat or mouse and the body fluids of the animal are thereafter studied. If a compound of formula (I)′ or a pharmacologically acceptable salt thereof can be detected in the body fluids, the compound under investigation is judged to be a pharmacologically acceptable ester or other derivative.

The compounds of formula (I)′ of the present invention can be converted to an ester, examples of which include a compound of formula (I)′ in which a hydroxyl group present therein is esterified. The ester residue may be a general protecting group where the esterified compound is to be used as an intermediate or a protecting group which is capable of being removed by a metabolic process (e.g. hydrolysis) in vivo where the esterified compound is one which is pharmacologically acceptable.

The compounds of Tables 1′ to 6′ are of general formula (I-1)′. The combinations of substituents (R^(1′), R^(2′) and R^(3′)) which are thus exemplified for (I-1)′ can also be applied to the general formulae (I-2)′, (I-3)′, (I-4)′ and (I-5)′, and compounds represented by the general formulae (I-2)′, (I-3)′, (I-4)′ and (I-5)′ which correspond to the compounds mentioned above as preferred compounds are also preferred.

Compounds of formula (I)′ of the present invention can be prepared by methods mentioned below.

Method A

Method A is a method for preparing a compound of formula (I)′ which is represented by the general formula (I-1)′

In the above formulae, R^(1′), R^(2′) and R^(3′) are as defined above.

Step A1

In this Step, a pyrrolidine compound of formula (3a)′ is prepared by reacting an aminonitrile compound of formula (1a)′ with an α,β-unsaturated aldehyde compound of formula (2a)′. This reaction is well known in the field of synthetic organic chemistry and can be carried out using well known techniques, for example according to the method described in EP 0799823, the contents of which are incorporated herein by reference thereto.

In more detail, this Step is carried out in the presence of a base. There is no particular restriction on the nature of the bases used, and any base commonly used in reactions of this type may equally be used here. Examples of such bases include: alkali metal hydroxides, such as lithium hydroxide, sodium hydroxide and potassium hydroxide; alkali metal hydrides, such as lithium hydride, sodium hydride and potassium hydride; alkali metal amides, such as lithium amide, sodium amide, potassium amide and lithium bis(trimethylsilyl)amide; and alkali metal alkoxides, such as lithium ethoxide, sodium methoxide, sodium ethoxide and potassium t-butoxide. Of these, we prefer the lithium amides.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include: aliphatic hydrocarbons, such as hexane and heptane; aromatic hydrocarbons, such as benzene, toluene and xylene; ethers, such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane; and alcohols, such as methanol, ethanol, propanol, isopropanol and butanol. Of these, we prefer the ethers.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −78° C. to 100° C., more preferably from −78° C. to room temperature. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 30 hours, more preferably from 1 hour to 20 hours, will usually suffice.

Step A2

In this Step, the desired pyrrole derivative of formula (I-1)′ of the present invention is prepared by the elimination of hydrogen cyanide and water from the compound of formula (3a)′ prepared in Step A1 above. These reactions are well known in the field of synthetic organic chemistry and can be carried out using well known techniques, for example according to the methods described in detail in EP 0799823.

In more detail, this may be achieved by heating the residue obtained by distilling off the solvent from the product of Step A1, or by heating the material obtained by extracting that residue, washing it with water and distilling off the solvent, preferably at a temperature not lower than 100° C., in the presence or absence of a solvent after completion of the reaction of Step A1. The reaction proceeds sufficiently in the absence of a solvent, but, when a solvent is used, the solvent is preferably inert and has a higher boiling point. Examples of suitable solvents include: toluene, xylene, dimethylformamide, dimethylacetamide, dimethyl sulfoxide, diglyme and diphenyl ether.

Method B, Method C, Method D and Method E

Method B, Method C, Method D and Method E are used to prepare compounds of formulae (I-2)′, (I-3)′, (I-4)′ and (I-5)′ respectively using the processes outlined in Reaction Schemes B to E below.

In the above formulae, R^(1′), R^(2′) and R^(3′) are defined above.

In the above Reaction Schemes Step B1, Step C1, Step D1 and Step E1 are carried out in a similar manner to Step A1 above, and Step B2, Step C2, Step D2 and Step E2 are carried out similarly to Step 2 above.

Method F

In this method; compounds of formula (I-1)′ of the present invention [(I-1a)′, (I-1b)′ and (I-1c)′] are prepared as shown in Reaction Scheme F.

In the above formulae, B′, D′, E′, R^(1′), R^(2′), R^(4′) and m have the same meanings as defined above,

-   -   R^(6′) represents a hydrogen atom, a lower alkyl group as         defined above or an aralkyl group as defined above, and     -   each R^(7′) is the same or different, and each represents a         hydrogen atom, a lower alkyl group as defined above, an aryl         group as defined above or an aralkyl group as defined above.         Step F1

In this Step, a pyrrole carboxylic acid derivative of formula (6)′ is prepared by reacting an α,β-unsaturated compound of formula (4)′ with an isonitrile compound of formula (5)′. Reactions of this type are well known in the field of synthetic organic chemistry and can be carried out using well known techniques, for example according to the methods described in detail in R. Di Santo et al., Synthetic Communications, 25(6), pp. 795-802 (1995), the contents of which are incorporated herein by reference thereto.

Step F2

In this Step, a disubstituted pyrrole compound (7)′ is produced by first, where R^(6′) represents a lower alkyl group or an aralkyl group from the pyrrole-carboxylic acid ester (6)′, removing said protecting group R^(6′) to give the pyrrole-carboxylic acid compound (6)′ (wherein R^(6′) represents a hydrogen atom) and then performing a decarboxylation reaction on said compound. Decarboxylation reactions of this type are well known in the field of synthetic organic chemistry and can be carried out using well known techniques, for example according to the methods described in detail in N. Yoshida et al.: Yakugaku Zasshi, 93(5), 584-598 (1973) (the contents of which are incorporated herein by reference thereto) which employ heating under acidic, basic or neutral conditions; for example, it can be carried out using a solvent and an acid or base under conditions described below. When R^(6′) is a lower alkyl group or an aralkyl group, the deprotection reaction can be carried out using well known techniques according to the methods described in detail in T. W. Greene et al.: Protective Groups in Organic Synthesis, John Willey & Sons, Inc.

The decarboxylation reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include water and mixtures of water and an organic solvent, examples of which include aliphatic hydrocarbons such as pentane, hexane and heptane; aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride and dichloroethane; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane; alcohols such as methanol, ethanol, propanol, isopropanol, butanol, s-butanol, isobutanol and t-butanol; aprotic polar solvents such as N,N-dimethylformamide, N,N-dimethylacetamide and dimethyl sulfoxide; nitrites such as acetonitrile; and esters such as methyl acetate and ethyl acetate, of which water, alcohols or a mixture thereof is preferred.

The acid to be used in the decarboxylation reaction is not particularly limited provided that it is one that is conventionally used as an acid in hydrolysis reactions, and examples thereof include mineral acids such as hydrochloric acid, sulfuric acid and phosphoric acid; carboxylic acids such as formic acid, acetic acid, propionic acid and trifluoroacetic acid; and sulfonic acids such as methanesulfonic acid and ethanesulfonic acid, of which hydrochloric acid, sulfuric acid or acetic acid is preferred.

The base to be used in the decarboxylation reaction is not particularly limited provided that it is one that is conventionally used as a base in hydrolysis reactions, and examples thereof include alkali metal hydrides such as sodium hydride and lithium hydride; alkali metal hydroxides such as sodium hydroxide and potassium hydroxide; alkali metal carbonates such as sodium carbonate and potassium carbonate; and amines such as triethylamine, tributylamine, pyridine, picoline and 1,8-diazabicyclo[5.4.0]undec-7-ene, of which sodium hydroxide or potassium hydroxide is preferred.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −20° C. and 150° C., and preferably between 0° C. and 100° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 48 hours, and preferably from 30 minutes to 12 hours is usually sufficient.

Steps F3 to F5

In Step F3, a silylated compound (8)′ is produced by silylating a nitrogen atom at the 1-position of the disubstituted pyrrole compound (7)′ obtained according to the method of Step F2.

In Step F4, the silylated compound (8)′ obtained according to the method of Step F3 is converted into a brominated pyrrole compound (9)′ using a brominating agent (e.g. N-bromosuccinimide); and, in Step F5, the isolated compound (9)′ thus obtained is first lithiated and then reacted with a heterocyclyl ketone (10)′ to afford a hydroxyheterocyclyl compound (11)′.

The reactions of Steps F3, F4 and F5 can be carried out according to conventional techniques known in the field of synthetic organic chemistry, such as the methods described in detail in Brian L. Bray et al., J. Org. Chem., 55, 6317-6318 (1990), the contents of which are incorporated herein by reference thereto.

Step F6

In this Step, an unsaturated heterocyclyl compound (12)′ is prepared by subjecting the hydroxyheterocyclyl compound (11)′ obtained in Step F5 to a dehydration reaction. The dehydration reaction is well known in the field of synthetic organic chemistry and can be carried out using well known techniques. For example, it can be carried out in the presence of an acid catalyst such as sulfuric acid, a solid catalyst such as alumina or a halogenation agent such as thionyl chloride [these reactions are described in detail, for example, in G. H. Coleman & H. F. Johnstone, Org. Synth., I, 183 (1941); R. L. Sawyer & D. W. Andrus, Org. Synth., III, 276 (1955); and J. S. Lamos et al., Tetrahedron Lett., 599 (1971), the contents of which are incorporated herein by reference thereto]. Alternatively, the dehydration reaction in this step can be performed by reaction of the hydroxyheterocyclyl compound (11)′ with a trialkylsilane, such as triethylsilane, tripropylsilane or tributylsilane, and trifluoroacetic acid [see, for example, Francis A. Carey & Henry S. Tremper, J. Am. Chem. Soc., 91, 2967-2972 (1969), the contents of which are incorporated herein by reference thereto].

Step F7

In this Step, the desired compound of formula (I-1a)′ of the present invention is prepared by removing the protecting group (the silyl group) from the pyrrole nitrogen of the unsaturated heterocyclyl compound (12)′ prepared in Step F6. Desilylation reactions of this type are well known in the field of synthetic organic chemistry and can be carried out using well known techniques, for example using a desilylating reagent such as tetrabutylammonium fluoride (TBAF) according to the procedure described in detail in Brian L. Bray et al., J. Org. Chem., 55, 6317-6318 (1990), the contents of which are incorporated herein by reference thereto.

Step F8

In this Step, an unsaturated heterocyclyl compound (13)′ is prepared by subjecting the hydroxyheterocyclyl compound (11)′ obtained in Step F5 to a dehydration reaction. This dehydration reaction is carried out in a manner similar to that described for Step F6 above.

Step F9

In this Step, the desired compound of formula (I-1b)′ of the present invention is prepared by removing the protecting group (the silyl group) from the pyrrole nitrogen of the unsaturated heterocyclyl compound (13)′ prepared in Step F8. This Step can be performed in a manner similar to that described for Step F7 above.

Step F10

In this Step, a hydroxyheterocyclyl compound (15)′ is prepared by first lithiating the compound (9)′ prepared in Step F4 and then reacting it with a heterocyclyl ketone (14)′. This Step can be carried out in a manner similar to that described for Step F5 above.

Step F11

In this Step, an unsaturated heterocyclyl compound (16)′ is prepared by subjecting the hydroxyheterocyclyl compound (15)′ obtained in Step F10 to a dehydration reaction. This dehydration reaction is carried out in a manner similar to that described for Step F6 above.

Step F12

In this Step, the desired compound of formula (I-1c)′ of the present invention is prepared by removing the protecting group (the silyl group) from the pyrrole nitrogen of the unsaturated heterocyclyl compound (16)′ prepared in Step F11. This Step can be performed in a manner similar to that described for Step F7 above.

Method G

Generally, the compounds of formula (I)′ of the present invention can be prepared by introducing the R³ group into a pyrrole compound already substituted on the pyrrole ring with the R^(1′) group and R² group. Compounds of formula (I-1)′ can be prepared, for example, according to the Method G, as shown in Reaction Scheme G below.

In the above formulae, R^(1′), R^(2′), R^(3′) and R^(7′) are as defined above, and L′ represents a leaving group.

The leaving group L′ is a group which is capable of leaving as a nucleophilic residue. Examples include halogen atoms such as fluorine, chlorine, bromine and iodine, trihalogenomethyloxy groups such as trichloromethoxy, lower alkanesulfonyloxy groups such as methanesulfonyloxy and ethanesulfonyloxy groups, lower halogeno alkane sulfonyloxy groups such as trifluoromethanesulfonyloxy and pentafluoroethanesulfonyloxy groups, and arylsulfonyloxy groups such as benzenesulfonyloxy, p-toluenesulfonyloxy and p-nitrobenzenesulfonyloxy groups. Of these, halogen atoms are preferred, and bromine atoms are particularly preferred.

Step G1

In this Step, a compound of formula (18)′ is prepared by first lithiating a bromopyrrole compound of formula (9)′ (prepared as described in Step F4 above) and then reacting the lithiated intermediate with a compound of formula (17)′ in a manner similar to Step F5 above. Substitution reactions of a lithiated pyrrole intermediate of this type are well known in the field of synthetic organic chemistry and can be carried out using well known techniques, for example according to the methods described in detail in WO 99/01449, the contents of which are incorporated herein by reference thereto.

Step G2

In this Step, a compound of formula (I-1)′ of the present invention is prepared by removing the protecting group (silyl group) of the compound of formula (18)′ obtained in Step G1 above according to a procedure similar that described in Step F7 above.

Method H

In this method, compounds of formula (Ia)′ of the present invention wherein R² is a heteroaryl group which has at least one ring nitrogen atom and which is substituted with a group of formula NR^(a′)R^(b′) can be prepared, as shown in Reaction Scheme H below.

In the above formulae, the cyclic group A′, R^(1′), R^(3′), R^(a′) and R^(b′) are defined above, R^(2″) is a heteroaryl group which has at least one ring nitrogen atom and L″ represents a leaving group, such that the group —R^(2″)-L″ represents a heteroaryl group which has at least one ring nitrogen atom (as defined and exemplified above for the substituent R^(2′)) which is substituted with a leaving group (e.g. 2-methanesulfonylpyrimidin 4-yl, 2-methanesulfonylpyridin-4-yl or the like).

The leaving group L″ is a similar group to the leaving groups defined and exemplified above in the definition of L′ or it is a lower alkylsulfonyl group as defined and exemplified above, such as a methanesulfonyl, ethanesulfonyl, propanesulfonyl or butanesulfonyl group, or an arylsulfonyl group, such as a benzenesulfonyl, p-toluenesulfonyl or p-nitrobenzenesulfonyl group. The group L″ is preferably a lower alkylsulfonyl group, and more preferably a methanesulfonyl group.

Step H1

In this Step, the desired compound of formula (Ia)′ of the present invention is prepared by reacting a compound of formula (19)′ with an amine compound of formula (20)′ to replace the leaving group with a group of formula —NR^(a′)R^(b′). This reaction is usually carried out in a solvent in the presence or absence of a base.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include: alcohols such as methanol, ethanol, propanol and isopropanol; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane; aprotic polar solvents such as dimethylformamide, dimethylacetamide and dimethylsulfoxide; nitriles such as acetonitrile; esters such as methyl acetate and ethyl acetate; aromatic hydrocarbons such as benzene, toluene and xylene; and aliphatic hydrocarbons such as pentane, hexane and heptane, of which alcohols are preferred and methanol and ethanol are more preferred.

The base to be used in this step is not particularly limited, as long as it is effective in such reactions, and examples include: alkali metal alkoxides such as sodium methoxide, sodium ethoxide and potassium t-butoxide; alkali metal hydrides such as sodium hydride and lithium hydride; alkali metal hydroxides such as sodium hydroxide and potassium hydroxide; alkali metal carbonates such as sodium carbonate and potassium carbonate; and amines such as triethylamine, tributylamine, pyridine, picoline and 1,8-diazabicyclo[5.4.0]undec-7-ene, of which amines are preferred, and triethylamine, pyridine and 1,8-diazabicyclo[5.4.0]undec-7-ene are more preferred.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −20° C. and 150° C., and preferably between 0° C. and 100° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 48 hours, and preferably from 30 minutes to 12 hours is usually sufficient.

Nearly all of the starting materials used in Methods A to H above, namely compounds (1a)′, (1b)′, (1c)′, (1d)′, (1e)′, (2a)′, (2b)′, (2c)′, (2d)′, (2e)′, (4)′, (5)′, (10)′, (14)′, (17)′ and (20)′, are either known compounds or they are compounds which can be prepared easily from known compounds by known methods (for example, the methods described in WO 97/5877), while the compound (19)′ can be synthesized from known compounds by performing reactions in a manner similar to that described in each of Methods A to E above.

However, in general, we find it convenient to carry out the reaction at a temperature of from −20° C. and 150° C., and preferably between 0° C. and 100° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 48 hours, and preferably from 30 minutes to 12 hours is usually sufficient.

Pollet et al., Heterocycles, 43, 1391 (1996) or Anet et al., Austral. J. Scient. Res., <A>3, 635-640 (1950), the contents of which are incorporated herein by reference thereto.

The amino protecting group in the definition of R^(14′) can be any protecting group for an amino group which is commonly used in organic synthesis, examples of which are found in T. W.

Step K1

In this Step, an α,β-unsaturated ketone derivative of formula (35)′ is prepared by reacting a cyclic amino acid derivative of formula (33)′ with a Grignard reagent of an olefin compound of formula (34)′. Reactions of this type are well known for the preparation of ketones from carboxylic acid derivatives and Grignard reagents, and any such reaction known in the field of organic synthesis can be employed; for example, it can be carried out using the procedures described in detail in H.

Steps K2 and K3

In Step K2, the nitrogen protecting group (R^(14′)) in the α,β-unsaturated ketone derivative of formula (35)′ prepared in Step K1 above is removed to afford a deprotected intermediate of formula (36)′ which is then cyclized in Step K3 to give the desired cyclic aminoketone compound of formula (37)′. In Step K2, the deprotection reaction employed can be any which is conventionally used in organic synthesis (examples of which are described in T. W. Greene et al., Protective Groups in Organic Synthesis, John Willey & Sons, Inc.). Preferably, the deprotection reaction is conducted under neutral or acidic conditions. After the deprotection reaction, the resulting product of formula (36)′, which is not isolated, cyclizes immediately to give the desired aminoketone compound of formula (37)′. The deprotection reaction is more preferably conducted under acidic conditions, and the aminoketone compound of formula (37)′ is prepared without further reaction by neutralizing the reaction mixture.

These steps can be carried out in a manner similar to the reactions described in Steps K2 and K3 above.

The starting compound of formula (38)′ used as the starting material in this method is either a known compound or it can be prepared from a known compound using known methods [for example, the methods described in S. W. Goldstein et al., J. Org. Chem., 57, 1179-1190 (1992); and B. Achille et al., J. Comb. Chem., 2, 337-340 (2000), the contents of which are incorporated herein by reference thereto].

In the above formulae, R^(4a′), R^(6′), R^(14′) and B′ are as defined above, and

-   -   R^(15′), R^(16′) are the same or different, and each represents         a hydrogen atom, a lower alkyl group as defined above or an         aralkyl group as defined above; or R^(15′) and R^(16′), together         with the nitrogen atom to which they are attached, form a 5- or         6-membered heterocyclic ring which includes one ring nitrogen         atom and which may optionally include one further heteroatom         selected from oxygen, sulfur and nitrogen atoms (examples of         such groups include pyrrolidinyl, piperidyl, piperazinyl,         morpholinyl and thiomorpholinyl groups).         Steps M1 and M2

In these Steps, a ketolactam compound d of formula (43)′ is prepared by first removing the amino protecting group (R^(14′)) from an α-ketoacid compound of formula (41)′ to afford a deprotected intermediate of formula (42)′, and then cyclizing said intermediate. These steps are conducted in a manner similar to that described in Steps K2 and K3 above.

Step M3

In this Step, a cyclic enaminolactam compound of formula (45)′ is prepared by reacting the ketolactam compound of formula (43)′ prepared in Step M2 above with a secondary amine compound of formula (44)′. Any of the techniques conventionally used in the field of organic synthetic chemistry for the preparation of enamine derivatives can be employed. For example, the step can be carried out according to the procedure described in G. Stork et al., J. Am, Chem. Soc., 85, 207 (1963) (the contents of which are incorporated-herein by reference thereto) or as described below.

The reaction is usually carried out in a solvent in the presence or absence of an acid.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include: aliphatic hydrocarbons such as pentane, hexane and heptane; aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride and dichloroethane; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane; alcohols such as methanol, ethanol, propanol, isopropanol, butanol, s-butanol, isobutanol and t-butanol; aprotic polar solvents such as N,N-dimethylformamide, N,N-dimethylacetamide and dimethyl sulfoxide; nitriles such as acetonitrile; and esters such as methyl acetate and ethyl acetate, of which ethers are preferred.

The acid to be used in the reaction is not particularly limited provided that it is one that is usually used in such reactions, and examples thereof include: inorganic acids such as hydrogen chloride, hydrogen bromide, sulfuric acid, perchloric acid and phosphoric acid; and organic acids such as acetic acid, formic acid, oxalic acid, methanesulfonic acid, p-toluenesulfonic acid, trifluoroacetic acid and trifluoromethanesulfonic acid. Of these, sulfuric acid, hydrochloric acid and p-toluensulfonic acid are preferred.

The reaction of this step can be carried out efficiently by removing water produced during the reaction by using molecular sieves or a water separator (for example, a Dean Stark Water Separator which can be obtained from Aldrich).

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −20° C. and 150° C., and preferably between 0° C. and 100° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 48 hours, and preferably from 30 minutes to 12 hours is usually sufficient.

Step M4

In this Step, a cyclic enamine compound of formula (46)′ is produced by reducing the cyclic enaminolactam compound of formula (45)′ prepared in Step M3 above. Any of the techniques conventionally used in the field of organic synthetic chemistry for performing reduction reactions can be employed. For example, the reduction can be carried out according to the procedures described in S. Cortes et al., J. Org. Chem., 48, 2246 (1983); Y. Tsuda et al., Synthesis, 652 (1977); H. C. Brown et al., J. Am. Chem. Soc., 86, 3566 (1964) and R. J. Sundberg et al., J. Org. Chem., 46, 3730 (1981) (the contents of which are incoporated herein by reference thereto); or, alternatively, can be performed as described below.

This reaction is usually carried out in a solvent in the presence of a reducing reagent.

Examples of the reducing reagent to be employed include hydride reagents such as alkali metal borohydrides e.g. sodium borohydride and lithium borohydride, and aluminum hydrides e.g. lithium aluminum hydride and lithium triethoxyaluminohydride; a combination of a Lewis acid such as aluminum chloride, tin-tetrachloride or titanium tetrachloride and a hydride reagent as defined above; and boron compounds such as diborane, of which lithium aluminium hydride is preferred.

In the reduction reaction, non-polar solvents can be used, preferred examples of which include: aliphatic hydrocarbons such as pentane, hexane and heptane; aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride and dichloroethane; and ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane, of which ethers are preferred.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −20° C. and 150° C., and preferably between 0° C. and 100° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 48 hours, and preferably from 30 minutes to 12 hours is usually sufficient.

Step M5

In this Step, the desired cyclic aminoketone compound of formula (47)′ is obtained by hydrolizing the cyclic, enamine compound of formula (46)′ prepared in Step M4 above. This reaction is performed by bringing the cyclic enamine compound of formula (46)′ into contact with water in the presence or absence of a solvent with or without the addition of an acid or base.

The reaction is normally and preferably effected in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of suitable solvents include water, or a mixture of water and an organic solvent (examples of which include: aliphatic hydrocarbons such as pentane, hexane and heptane; aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride and dichloroethane; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane; alcohols such as methanol, ethanol, propanol, isopropanol, butanol, s-butanol, isobutanol and t-butanol; aprotic polar solvents such as N,N-dimethylformamide, N,N-dimethylacetamide and dimethyl sulfoxide; nitriles such as acetonitrile; and esters such as methyl acetate and ethyl acetate), of which water, a mixture of water and an alcohol and a mixture of water and an ether are preferred.

The acid to be used is not particularly limited provided that it is one that is usually used as an acid in hydrolysis reactions, and examples thereof include mineral acids such as hydrochloric acid, sulfuric acid and phosphoric acid; carboxylic acids such as formic acid, acetic acid, propionic acid and trifluoroacetic acid; and sulfonic acids such as methanesulfonic acid and ethanesulfonic acid, of which hydrochloric acid, sulfuric acid and acetic acid are preferred.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −20° C. and 150° C., and preferably between 0° C. and 100° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 48 hours, and preferably from 30 minutes to 12 hours is usually sufficient.

Method N

The compound of formula (45)′, which is an intermediate in the preparation of the cyclic aminoketone compound of formula (47)′ in Method M above, can also be produced by Method N according to Reaction Scheme N below.

In the above formulae, B′, R^(4a′), R^(8′), R^(9′), R^(15′) and R^(16′) are as defined above, and R^(17′) represents a hydrogen atom or a carboxyl protecting group.

The carboxyl protecting group in the definition of R^(17′) can be any such protecting group conventionally used in the organic chemistry; preferably, it is a lower alkyl group as defined above or an aralkyl group as defined above.

Step N1

In this Step, an aminodiester compound of formula (50)′ is produced by the reaction of a cyclic amino acid ester compound of formula (48)′ with a malonic acid derivative of formula (49)′ or a reactive derivative thereof. Any of the techniques conventionally used in the field of organic synthetic chemistry for amidation reactions can be employed, and this step can, for example, be carried out in the manner described in processes (a), b) and (c) described below.

(a) When R^(17′) is a hydrogen atom, the reaction is conducted in a solvent in the presence of a condensing agent and in the presence or absence of a base.

There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or on the reagents involved and that it can dissolve the reagents, at least to some extent. Examples of the solvent to be employed include: aliphatic hydrocarbons such as pentane, hexane and heptane; aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as dichloromethane, chloroform, carbon tetrachloride and dichloroethane; ethers such as diethyl ether, diisopropyl ether, tetrahydrofuran and dioxane; alcohols such as methanol, ethanol, propanol, isopropanol, butanol, s-butanol, isobutanol and t-butanol; aprotic polar solvents such as N,N-dimethylformamide, N,N-dimethylacetamide and dimethyl sulfoxide; nitriles such as acetonitrile; esters such as methyl acetate and ethyl acetate; water; or a mixture of these solvents described above, of which halogenated hydrocarbons, ethers and esters are preferred and dichloromethane, tetrahydrofuran and ethyl acetate are more preferred.

Any suitable condensing agent that is conventionally employed in such reactions can be employed, and examples include dicyclohexylcarbodiimide, 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide, N,N′-carbonyldiimidazole and the like.

The base to be used is not particularly limited provided that it is one that is usually used as a base in such reactions, and examples thereof include alkali metal alkoxides such as sodium methoxide, sodium ethoxide and potassium t-butoxide; alkali metal hydrides such as sodium hydride and lithium hydride; alkali metal hydroxides such as sodium hydroxide and potassium hydroxide; alkali metal carbonates such as sodium carbonate and potassium carbonate; and amines such as triethylamine, tributylamine, pyridine, picoline and 1,8-diazabicyclo[5.4.0]undec-7-ene, of which amines are preferred, and triethylamine, pyridine and 1,8-diazabicyclo-[5.4.0]undec-7-ene are more preferred.

The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the solvent, and the starting material or reagent used. However, in general, we find it convenient to carry out the reaction at a temperature of from −20° C. and 150° C., and preferably between 0° C. and 100° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed. However, provided that the reaction is effected under the preferred conditions outlined above, a period of from 10 minutes to 48 hours, and preferably from 30 minutes to 12 hours is usually sufficient.

Alternatively, where R^(17′) is a hydrogen atom, the reaction of Step N1 can also be carried out by converting the compound of formula (49)′ into a reactive derivative thereof followed by the procedure described in process (c) below.

(b) When R^(17′) is a carboxyl protecting group (preferably a lower alkyl group as defined above or an aralkyl group as defined above), the reaction is performed by heating in the presence or absence of a solvent.

When the reaction is conducted in a solvent, the same solvent as that described in process (a) can be used. The temperature for the reaction is between 30° C. and 100° C., preferably between the range of +5° C. of the boiling point of the solvent that is employed. Most preferably, the reaction is carried out by heating the reaction mixture under reflux.

When a solvent is not used in this reaction, the desired compound is prepared by heating a mixture of the compounds of formulae (48)′ and (49)′. The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. The preferred reaction temperature will depend upon such factors as the nature of the starting materials used. However, in general, we find it convenient to carry out the reaction at a temperature of from 30° C. and 150° C., and preferably between 50° C. and 120° C. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents and solvent employed.

TEST EXAMPLES

The biological activity of the compounds of the present invention is illustrated by the following Test Examples.

Test Example 1 Inhibition of the Production of the Cytokines IL-1β and TNFα In Vitro in Human Whole Blood

This test was performed according to the method of Hartman, et al. [D. A. Hartman, S. J. Ochalski and R. P. Carlson; The effects of anti-inflammatory and antiallergic drugs on cytokine release after stimulation of human whole blood by lipopolysaccharide and zymosan A: Inflamm. Res., 44, 269 (1995)].

Peripheral blood samples were collected in the presence of heparin from healthy adult volunteers. 1000 μl of whole blood were added to an Eppendorf tube to which 2 μl of a dimethyl sulfoxide solution of the test compound had been added in advance, after which 10 μl of lipopolysaccharide (E. coli O26: B6 origin, Difco) were added as a stimulant (final concentration of said lipopolysaccharide: 10 μg/ml). This was mixed well and then incubated for 6 hours at 37° C. in the presence of 5% CO₂. At the end of the incubation, the mixture was cooled to 4° C. to stop the reaction, followed immediately by centrifuging for 5 minutes at 14,000 rpm to separate and collect the supernatant plasma. The IL-1β and TNFα produced and released into the plasma were measured using a commercially available enzyme immunoassay (ELISA) kit [Cayman (IL-1β) and Genzyme (TNFα)]. The procedure was also repeated in the absence of test compound. The inhibitory effect [IC₅₀ (μM)] on the production of IL-1β and TNFα was determined from the amounts of the cytokines produced in the presence and absence of the test compound.

The results for the inhibition of the production in vitro of TNFα are shown in Table 3 below for the most preferred compounds of the present invention which are the subject of the original species claims. In this Table, Compounds A and B are as follows: TABLE 3

Table 3 above demonstrates excellent inhibitory activity against the production of TNFα in vitro for said most preferred compounds of the present invention.

The compounds of the present invention were also found to show excellent inhibitory activity against the production of IL-β in vitro.

Test Example 2 Inhibition of the Production of TNFα In Vivo

This test was performed according to the method of Ochalski, et al. [S. J. Ochalski, D. A. Hartman, M. T. Belfast, T. L. Walter, K. B. Glaser and R. P. Carlson; Inhibition of endotoxin-induced hypothermia and serum TNF-α levels in CD-1 mice by various pharmacological agents: Agents Actions 39, C52-C54 (1993)].

The production of TNFα was induced in mice by the intravenous injection of lipopolysaccharide (E. coli O26: B6 origin, Difco) which was prepared to a concentration of 0.045 mg/ml using physiological saline. The saline preparation of lipopolysaccharide was administered at the rate of 10 ml/l kg of body weight into the caudal vein of Balb/c mice (males, age 5-7 weeks, body weight: approx. 22 g, Japan Charles River) which had been fasted overnight starting on the day before the experiment. One hour after administration, the mice were laparotomized under ether anaesthesia and blood was collected from the abdominal vena cava. Blood collection was performed using a 1 ml volume disposable syringe equipped with a 23 G needle which had been moistened with heparin on the inside wall. Following blood collection, the blood was immediately transferred to a 1.5 ml volume Eppendorf tube and centrifuged at 4° C. and 14,000 rpm to separate the plasma. This plasma was then stored at −20° C. until measurement of TNFα. The measurement of the amount of TNFα was performed with a commercially available enzyme immunoassay (ELISA) kit (Mouse TNFα ELISA KIT, Genzyme).

To determine the inhibitory activity of the test compounds, each test compound was suspended in a 0.5% tragacanth solution and then administered orally to the Balb/c mice at the rate of 10 ml/1 kg of body weight 30 minutes before injection of lipopolysaccharide. The level of TNFα production was then determined as described above. In the control group, 0.5% tragacanth solution was administered at the rate of 10 ml/1 kg of body weight to the test mice instead of the solutions of the test compounds. A minimum of 3 dose levels of the test compound was administered to groups of 5 test mice for each test compound. The inhibitory rate relative to the control group was calculated for each dose level. From the inhibitory rates and the dosages, ID₅₀ values were calculated by the least squares method.

The compounds of the present invention were found to show excellent inhibitory activity against the production of TNFα in vivo.

Test Example 3 Inhibition of the Production of IL-1β In Vivo

This test was performed according to the method of Griffiths, et al. [Richard J. Griffiths, Ethan J. Stam, James T. Downs and Ivan G. Otterness; ATP Induces the Release of IL-1 from LPS-Primed Cells In Vivo: J. Immunol., 154, 2821-2828 (1995)].

The production of IL-1 was induced in mice by the intraperitoneal injection of lipopolysaccharide followed by the intraperitoneal injection of adenosine triphosphate (ATP). This was achieved by first administering a solution of lipopolysaccharide (E. coli O26: B6 origin, Difco), which had been prepared to a concentration of 0.0045 mg/ml using physiological saline, at the rate of 10 ml of said saline solution/1 kg of body weight into the peritoneal cavity of Balb/c mice (males, age 5-7 weeks, body weight: approx. 22 g, Japan Charles-River) which had been fasted overnight starting on the day before the experiment. Two hours later, 0.5 ml of ATP, which had been prepared to a concentration of 6.03 mg/ml using physiological saline, were administered into the peritoneal cavity. 0.5 hours after the administration of ATP, the mice were sacrificed by suffocation using dry ice followed immediately by intraperitoneal injection of 3 ml of washing phosphate buffer solution [containing heparin (10 U/ml), p-toluenesulfonyl fluoride (0.25 mM), leupepsin (1 μg/ml), pepstatin (1 μg/ml) and EDTA (1 mM)] to wash the peritoneal cavity. A 1 ml volume disposable syringe equipped with a 21 G needle was then used to recover the washing liquid. After the recovery, the washing liquid from the peritoneal cavity was immediately transferred to a 1.5 ml volume Eppendorf tube and centrifuged at 4° C. and 7,500 rpm to separate the supernatant. This supernatant was then stored at −20° C. until measurement of IL-1β.

The measurement of the amount of IL-1β was performed with an enzyme immunoassay (ELISA) kit (Mouse IL-1β ELISA KIT, Genzyme).

To determine the inhibitory activity of the test compounds, each test compound was suspended in a 0.5% tragacanth solution and then administered orally to the Balb/c mice at the rate of 10 ml/1 kg of body weight 30 minutes before injection of lipopolysaccharide. The level of TNFα production was then determined as described above. In the control group, 0.5% tragacanth solution was administered to the test mice at the rate of 10 ml/1 kg of body weight instead of the solutions of the test compounds. A minimum of 3 dose levels of the test compound was administered to groups of 5 test mice for each test compound. The mean inhibitory rate relative to the control group was calculated for each dose level.

In this test, the compounds of the present invention demonstrated an excellent inhibitory effect against the production of IL-1β in vivo.

Test Example 4 Activity in Preventing the Development of Adjuvant-Induced Arthritis In Vivo

The test was performed according to the method described by Winder et al. (Arthritis Rheum., 12, 472-482, 1969).

Heat-killed dried Mycobacterium butyricum (Difco Laboratories, Lot 679123) was ground on an agate mortar, and was then suspended in dry-sterilised liquid paraffin (first grade, Wako Pure Chemical Industries, Ltd.) to make a 2 ml suspension. The resulting suspension was then sonicated and used as an adjuvant. Arthritis was induced by the intradermal injection of the adjuvant (100 μg of heat killed dried bacterium/0.05 ml of paraffin/paw) into the heel of the right hind paw of a Lewis rat (male, age 8 weeks, Japan Charles River). The test compounds, which had been suspended in 0.5% sodium carboxymethyl cellulose solution (CMC, Daiichi Pure Chemicals, Co., Ltd.), were administered orally once a day from the day of injection of the adjuvant (day 0) to day 20.

The volumes of the injected (right) and non-injected (left) hind paws were measured on days 3, 5, 7, 10, 13, 15, 18 and 21 using a Plethysmometer™ (Ugo Basile), the hind paws being soaked from the toe to the hairline in the bath of the Plethysmometer™. The volumes of the swollen feet (adjuvant-injected right hind foot volume−non-injected left hind foot volume) were calculated. The percent inhibition of swelling of the injected foot of the treated animals as compared to that of the control animals on day 21 was calculated as follows. Inhibition (%)={1−(swollen foot volume of compound-treated animals)/(swollen foot volume of control animals)}×100

A linear regression curve was obtained from the percent inhibition and the logarithmic value of the dosage by the least squares method. ID₅₀ values were calculated using this curve.

In this test, the compounds of the present invention showed excellent activity in preventing the development of adjuvant-induced arthritis.

Test Example 5 Activity in Preventing the Development of Arthritis Induced by Anti-Collagen Antibody In Vivo

In this test, an anti-collagen antibody-induced mouse arthritis model was employed.

0.5 ml (2 mg of antibody) of an anti-collagen antibody solution (4 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were injected into the caudal vein of Balb/c mice (males, age 5-6 weeks old, Japan Charles River). Three days after injection, 0.1 ml [0.05 mg of lipopolysaccharide] of a lipopolysaccharide solution (0.5 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were administered to the mice by intraperitoneal injection.

The test compounds, which had been suspended in 0.5% tragacanth were administered orally to the test animals at the rate of 10 ml/1 kg of body weight once per day for 7 days from the day when the anti-collagen antibody was administered. To the mice of the control group, 0.5% tragacanth solution was administered at the rate of 10 ml/kg of body weight once per day for 7 days from the day when the anti-collagen antibody was administered, instead of solutions of the test compounds.

After the administration of the test compounds (or 0.5% tragacanth solution), the degree of edema in the 4 paws of each test mouse was scored according to the following basis:

-   -   0: normal (edema is not observed);     -   1: edema is observed in one of the five toes;     -   2: edema is observed in two or more of the five toes;     -   3: the whole of the paw is swollen.

The degree of arthritis in the test mouse was evaluated by the total of the edema scores in the 4 paws. The rate of suppression was calculated from the degrees of arthritis of the control animals and of the animals treated with the test compounds. From the rates of suppression and the dosages, ID₅₀ values were calculated by the least squares method.

In this test, the compounds of the present invention showed excellent activity in preventing the development of arthritis induced by anti-collagen antibody.

Test Example 6 Activity in Treating Arthritis Induced by Anti-Collagen Antibody In Vivo

In this test, an anti-collagen antibody-induced mouse arthritis model was employed.

0.5 ml (2 mg of antibody) of an anti-collagen antibody solution (4 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were injected into the caudal vein of Balb/c mice (males, age 5-6 weeks old, Japan Charles River). Three days after injection, 0.1 ml [0.05 mg of lipopolysaccharide] of a lipopolysaccharide solution (0.5 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were administered to the mice by intraperitoneal injection.

7 days after the administration of the anti-collagen antibody solution, the degree of edema in the 4 paws of each test mouse was scored according to the basis as shown in Test Example 5 above.

Those mice in which edema in both the hind paws had been scored as “3” were selected. Test compounds, which had been suspended in 0.5% tragacanth solution, were administered orally to the selected mice at the rate of 10 ml/kg of body weight once per day for 3 days. To the mice of the control group, 0.5% tragacanth solution was administered at the rate of 10 ml/kg of body weight once per day for 3 days instead of solutions of the test compounds.

After the administration of the test compounds (or 0.5% tragacanth solution), the degree of arthritis in each test mouse was evaluated in the same manner as described in Test Example 5. The rates of treatment of arthritis induced by anti-collagen antibody were calculated from the degrees of arthritis of the control animals and of the compound-treated animals.

From the rates of treatment and the dosages, ID₅₀ values were calculated by the least squares method.

In this test, the compounds of the present invention showed excellent activity in treating arthritis induced by anti-collagen antibody.

TEST EXAMPLES Test Example 1′ Inhibition of the Production of the Cytokines IL-1β and TNFα In Vitro in Human Whole Blood

This test was performed according to the method of Hartman, et al. [D. A. Hartman, S. J. Ochalski and R. P. Carlson; The effects of anti-inflammatory and antiallergic drugs on cytokine release after stimulation of human whole blood by lipopolysaccharide and zymosan A: Inflamm. Res., 44, 269 (1995)].

Peripheral blood samples were collected in the presence of heparin from healthy adult volunteers. 1000 μl of whole blood were added to an Eppendorf tube to which 2 μl of a dimethyl sulfoxide solution of the test compound had been added in advance, after which 10 μl of lipopolysaccharide (E. coli O26: B6 origin, Difco) were added as a stimulant (final concentration of said lipopolysaccharide: 10 μg/ml). This was mixed well and then incubated for 6 hours at 37° C. in the presence of 5% CO₂. At the end of the incubation, the mixture was cooled to 4° C. to stop the reaction, followed immediately by centrifuging for 5 minutes at 14,000 rpm to separate and collect the supernatant plasma. The IL-1β and TNFα produced and released into the plasma were measured using a commercially available enzyme immunoassay (ELISA) kits [Cayman (IL-1β) and Genzyme (TNFα)]. The procedure was also repeated in the absence of test compound. The inhibitory effect [IC₅₀ (μM)] on the production of IL-1β and TNFα was determined by the method of least squares from the amounts of the cytokines produced in the presence and absence of the test compound. The results for the inhibitory effect on TNFα production are as shown in Table 7′ below.

Test Example 2′ Inhibition of the Production of TNFα In Vivo

This test was performed according to the method of Ochalski, et al. [S. J. Ochalski, D. A. Hartman, M. T. Belfast, T. L. Walter, K. B. Glaser and R. P. Carlson; Inhibition of endotoxin-induced hypothermia and serum TNF-α levels in CD-1 mice by various pharmacological agents: Agents Actions 39, C52-C54 (1993)].

The production of TNFα was induced in mice by the intravenous injection of lipopolysaccharide (E. coli O26: B6 origin, Difco) which was prepared to a concentration of 0.045 mg/ml using physiological saline. The saline preparation of lipopolysaccharide was administered at the rate of 10 ml/1 kg of body weight into the caudal vein of Balb/c mice (males, age 5-7 weeks, body weight: approx. 22 g, Japan Charles River) which had been fasted overnight starting on the day before the experiment. One hour after administration, the mice were laparotomized under ether anaesthesia and blood was collected from the abdominal vena cava. Blood collection was performed using a 1 ml volume disposable syringe equipped with a 23 G needle which had been moistened with heparin on the inside wall. Following blood collection, the blood was immediately transferred to a 1.5 ml volume Eppendorf tube and centrifuged at 4° C. and 14,000 rpm to separate the plasma. This plasma was then stored at −20° C. until measurement of TNFα. The measurement of the amount of TNFα was performed with a commercially available enzyme immunoassay (E LISA) kit (Mouse TNFα ELISA KIT, Genzyme).

To determine the inhibitory activity of the test compounds, each test compound was suspended in a 0.5% tragacanth solution and then administered orally to the Balb/c mice at the rate of 10 ml/1 kg of body weight 30 minutes before injection of lipopolysaccharide. The level of TNFα production was then determined as described above. In the control group, 0.5% tragacanth solution was administered at the rate of 10 ml/1 kg of body weight to the test mice instead of the solutions of the test compounds. A minimum of 3 dose levels of the test compound was administered to groups of 5 test mice for each test compound. The inhibitory rate relative to the control group was calculated for each dose level. From the inhibitory rates and the dosages, ID₅₀ values were calculated by the least squares method, the results being shown in Table 9′ below. TABLE 9 Inhibitory Effect on TNFα Production (in vivo) Test compound ID₅₀ [mg/kg] Compound of Example 16 0.71 Compound of Example 31 0.36 Compound of Example 32 0.61 Compound of Example 43 0.40

As can be seen from Table 9′ above, the above-tested compounds of the present invention were found to show excellent inhibitory activity against the production of TNFα in vivo.

Test Example 3′ Inhibition of the Production of IL-1β In Vivo

This test was performed according to the method of Griffiths, et al. [Richard J. Griffiths, Ethan J. Stam, James T. Downs and Ivan G. Otterness; ATP Induces the Release of IL-1 from LPS-Primed Cells In Vivo: J. Immunol., 154, 2821-2828 (1995)].

The production of IL-1β was induced in mice by the intraperitoneal injection of lipopolysaccharide followed by the intraperitoneal injection of adenosine triphosphate (ATP). This was achieved by first administering a solution of lipopolysaccharide (E. coli O26: B6 origin, Difco), which had been prepared to a concentration of 0.0045 mg/ml using physiological saline, at the rate of 10 ml of said saline solution/1 kg of body weight into the peritoneal cavity of Balb/c mice (males, age 5-7 weeks, body weight: approx. 22 g, Japan Charles River) which had been fasted overnight starting on the day before the experiment. Two hours later, 0.5 ml of ATP, which had been prepared to a concentration of 6.03 mg/ml using physiological saline, were administered into the peritoneal cavity. 0.5 hours after the administration of ATP, the mice were sacrificed by suffocation using dry ice followed immediately by intraperitoneal injection of 3 ml of washing phosphate buffer solution [containing heparin (10 U/ml), p-toluenesulfonyl fluoride (0.25 mM), leupepsin (1 μg/ml), pepstatin (1 μg/ml) and EDTA (1 mM)] to wash the peritoneal cavity. A 1 ml volume disposable syringe equipped with a 21 G needle was then used to recover the washing liquid. After the recovery, the washing liquid from the peritoneal cavity was immediately transferred to a 1.5 ml volume Eppendorf tube and centrifuged at 4° C. and 7,500 rpm to separate the supernatant. This supernatant was then stored at −20° C. until measurement of IL-1β.

The measurement of the amount of IL-1β was performed with an enzyme immunoassay (ELISA) kit (Mouse IL-1β ELISA KIT, Genzyme).

To determine the inhibitory activity of the test compounds, each test compound was suspended in a 0.5% tragacanth solution and then administered orally to the Balb/c mice at the rate of 10 ml/1 kg of body weight 30 minutes before injection of lipopolysaccharide. The level of TNFα production was then determined as described above. In the control group, 0.5% tragacanth solution was administered to the test mice at the rate of 10 ml/1 kg of body weight instead of the solutions of the test compounds. A minimum of 3 dose levels of the test compound was administered to groups of 5 test mice for each test compound. The mean inhibitory rate relative to the control group was calculated for each dose level.

In this test, the compounds of the present invention that were tested demonstrated an excellent inhibitory effect against the production of IL-1β in vivo.

Test Example 4′ Activity in Preventing the Development of Adjuvant-Induced Arthritis In Vivo

The test was performed according to the method described by Winder et al. (Arthritis Rheum., 12, 472-482, 1969).

Heat-killed dried Mycobacterium butyricum (Difco Laboratories, Lot 679123) was ground on an agate mortar, and was then suspended in dry-sterilised liquid paraffin (first grade, Wako Pure Chemical Industries, Ltd.) to make a 2 mg/ml suspension. The resulting suspension was then sonicated and used as an adjuvant. Arthritis was induced by the intradermal injection of the adjuvant (100 μg of heat killed dried bacterium/0.05 ml of paraffin/paw) into the heel of the right hind paw of a Lewis rat (male, age 9 weeks, 190 g, Japan Charles River). The test compounds, which had been suspended in a 0.5% aqueous sodium carboxymethyl cellulose solution (CMC, Daiichi Pure Chemicals, Co., Ltd.), were administered orally at the rate of 5 ml/kg once a day from the day of injection of the adjuvant (day 0) to day 20.

The volumes of the right hind paw (adjuvant-injected paw) and left hind paw (non-injected paw) were measured on days 3, 5, 7, 10, 13, 15, 18 and 21 using a Plethysmometer™ (Ugo Basile), the hind paws being soaked from the toe to the hairline in the bath of the Plethysmometer™. The volumes of the swollen feet (adjuvant-injected right hind foot volume−non-injected left hind foot volume) were calculated. The percent inhibition of swelling of the injected foot of the treated animals as compared to that of the control animals on day 21 was calculated as follows. Inhibition (%) {1−(swollen foot volume of compound-treated animals)/(swollen foot volume of control animals)}×100

A linear regression curve was obtained from the percent inhibition and the logarithmic value of the dosage by the least squares method. ID₅₀ values were calculated using this curve, the results being shown in Table 10′ below. TABLE 10 Activity in Preventing the Development of Adjuvant-Induced Arthritis in vivo Test compound ID₅₀ [mg/kg] Compound of Example 12 2.1 Compound of Example 16 1.2

As can be seen from Table 10′ above, in this test, the above-tested compounds of the present invention showed excellent activity in preventing the development of adjuvant-induced arthritis.

Test Example 5′ Activity in Preventing the Development of Arthritis Induced by Anti-Collagen Antibody In Vivo

In this test, an anti-collagen antibody-induced mouse arthritis model was employed.

0.5 ml (2 mg of antibody) of an anti-collagen antibody solution (4 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were injected into the caudal vein of Balb/c mice (males, age 5-6 weeks old, Japan Charles River). Three days after injection, 0.1 ml [0.05 mg of lipopolysaccharide] of a lipopolysaccharide solution (0.5 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were administered to the mice by intraperitoneal injection.

The test compounds, which had been suspended in 0.5% tragacanth were administered orally to the test animals at the rate of 10 ml/1 kg of body weight once per day for 7 days from the day when the anti-collagen antibody was administered. To the mice of the control group, 0.5% tragacanth solution was administered at the rate of 10 ml/kg of body weight once per day for 7 days from the day when the anti-collagen antibody was administered, instead of solutions of the test compounds.

After the administration of the test compounds (or 0.5% tragacanth solution), the degree of edema in the 4 paws of each test mouse was scored according to the following basis:

-   -   0: normal (edema is not observed);     -   1: edema is observed in one of the five toes;     -   2: edema is observed in two or more of the five toes;     -   3: the whole of the paw is swollen.

The degree of arthritis in the test mouse was evaluated by the total of the edema scores in the 4 paws. The rate of suppression was calculated from the degrees of arthritis of the control animals and of the animals treated with the test compounds. From the rates of suppression and the dosages, ID₅₀ values were calculated by the least squares method.

In this test, the compounds of the present invention that were tested showed excellent activity in preventing the development of arthritis induced by anti-collagen antibody.

Test Example 6′ Activity in Treating Arthritis Induced by Anti-Collagen Antibody In Vivo

In this test, an anti-collagen antibody-induced mouse arthritis model was employed.

0.5 ml (2 mg of antibody) of an anti-collagen antibody solution (4 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were injected into the caudal vein of Balb/c mice (males, age 5-6 weeks old, Japan Charles River). Three days after injection, 0.1 ml [0.05 mg of lipopolysaccharide] of a lipopolysaccharide solution (0.5 mg/ml, Arthritogenic mAb Cocktail: product of Immuno-Biological Laboratories Co., Ltd) were administered to the mice by intraperitoneal injection.

7 days after the administration of the anti-collagen antibody solution, the degree of edema in the 4 paws of each test mouse was scored according to the basis as shown in Test Example 5′ above.

Those mice in which edema in both the hind paws had been scored as “3” were selected. Test compounds, which had been suspended in 0.5% tragacanth solution, were administered orally to the selected mice at the rate of 10 ml/kg of body weight once per day for 3 days. To the mice of the control group, 0.5% tragacanth solution was administered at the rate of 10 ml/kg of body weight once per day for 3 days instead of solutions of the test compounds.

After the administration of the test compounds (or 0.5% tragacanth solution), the degree of arthritis in each test mouse was evaluated in the same manner as described in Test Example 5′. The rates of treatment of arthritis induced by anti-collagen antibody were calculated from the degrees of arthritis of the control animals and of the compound-treated animals.

From the rates of treatment and the dosages, ID₅₀ values were calculated by the least squares method.

In this test, the compounds of the present invention that were tested showed excellent activity in treating arthritis induced by anti-collagen antibody.
